' AUTOMOBILE RADIA'roR.

Application led April 17, 1918, Serial No. 229,171. Renewed January 17,1923.

To all 'whom t may concern:

Be it known that I, ALBERT KLELL, a citizen of thev United States,residing at West Park, in the county of Cuyahoga and State of Ohio, haveinvented certain new and useful Improvements inl Automobile Radiators,of which the following is a specilication.

This invention relates to an improvement in an automobile radiator, andthe object is to provide a radiator having a plural number ofwater-.circulating sections or units which may be removed separatelymerely by unscrewing two nuts exposed at the front of the radiator body.Each unit consists of a column of disk cells of square outline, and eachcell is divided into two compartments by a perforated diaphragm, thuscausing the water to owin a thin stream from the center vto the edge ofeach cell and back to the center and thence into the neXt cell over asimilar circuitous course and so on through the column.

' In the accompanying drawings, Fig. 1 is a front view of a radiatorconstructed according to my invention, but showing only one-half of itsfull complement of watercirculating units removed, and Fig. 2 is asectional view of the top and bottom portions of a radiator body withthe water-circulating units removed, and Fig. 3 is a sectional view ofone of the units, but-shown shortened by omission ofcentral cells. Fig.4 is a side View of the radiator, partly in section, showing the unitsfastened in place. Fig. 5 is an enlarged sectional detail of one cellshowing the walls and diaphragm separated. Fig. 6 is a plan View of acell diaphragm.

The radiator comprises an open frame consisting of twowater-distributing compartments 2 and 3 whichsare rlgidly unlted itogether in spaced relation by narrow side walls forming a frame, in asense, within which the radiator units are adapted to be removablysecured. The bottom compartment 2 has a water outlet connection 5 at itsrear, and top compartment 3 is rovided with a water intake connection 6,a so at lts rear. Each compartment 2 and 3 hasy a channeled-or hollowoffset 7 at its rear extending inwardly which provides a vertical seator wall 8 transversely of the radiator, and the respective offsetsproject toward each other and rovide a recess in the front face of thera iator adapted to receive av series of water-circulating and coolingsections or .units 12. Thus,\the headsvl() and 1'1` at opposite ends ofeach water-circulating un1t 12 may be seated upon the retired wall 8 anda watertight joint made thereat by placing, suitable rubber gaskets 13between the meeting faces of the assembled parts. The means for clampingeach unit in place, consists of a bolt .14 extending through a tube 15within each odset 7, and the bolt is either screwed or seated in placeand eX- tends forward beyond the front face of the radiator; In thisway, each unit may be easily slipped into place from the front and alsoeasily removed. The heads or ends of each unit are hollow and each has acentral tube 17 extending therethrough from front to rear, and a recessor pocketv 18 is formed in the front face of each' head to receive thenut 16.

When assembled, the hollow interior of each unit head and thecompartments 2 and 3 are open to each other for a"free vflow of water,and a pair of nipples 19 is provided in wall 8 adjacent each bolt 14,each nipple having a flange secured to the inner side of the wall 8 andbeing projected forwardly to enter suitable openings in the rear fiatwall of .each head, and which openings necessarily correspond inposition to that of the nipples.

s Each water-circulatingunit 12 is a builtup or composite structure,consisting of the hollowheads or ends 10 andll built into a column ofdisk cells 21, having short necks sleeved and united together. Each cellcomprises two dished parts 22A and 23 of concavo-convex formation seamedtogether, and I insert a thin metal plate 24 centrally between the saidparts. This platehas a row of perforations 25 in its border and the bodyof the plate is also provided with rounded projections 26 struck up inopposite directions on radial lines, and these projections space theouter walls or sections 22 and 23 in definite distances apart and alsorevent complete collapse thereof. Each cell 1s made of thin metal, andthe diaphragm 24 having projections as described 4is of advantage inreinforcing the cell. The cell parts 22 and 23 have each a short neck,27, whereby a sleeved union may be made with an adjacent disk cell ofsimilar construction, in this way building up a column of such diskcells through which the water is-adapted to circulate in a circuitouscourse beginning at the vcell. i

ycenter lof each disk cell and passing to the outer edge thereof, thencethrough the perorations in the diaphragm and back throu hythe upperchamber to the center of the yce l where communication is establishedwith the" next adjacent orisuperposed disk i The water circulat'ingunit.as thus constructed is strong durable, and alsol suliiciently flexibleto withstand any ,expansion or contraction-to which itfmay be subjected,and itis-falso Well adapted to withstand the shocks and vibrations metwith when used in anv automobile radiator. I

have shown ythe disk cells as square so that a "solid'bankof ksuch cellsmay be placed in close juxtaposition-w'ithin theo yen frame of theradiator, and when so p aced'each:` disk cell separated slightly fromthe next and/ air aces are provided from front-to rear of the radiatorand all of the cell surfaces are exposed to the cooling influence'of Ythev air passing through the radiator.

What4 I claim is:

1. 'A radiator comprising separate water compartments at its top and atits bottom having sheet metal 'walls oii'set inwardly toprovidetransverse recesses and vertical seats facing the `front side ofthe radiator and water passages therein at the rear side of saidrecesses and seats, said vertical seats having a` series of elongateddepressions therein and a plurality of spaced openings at kthe base ofeach of said depressions, in combination with` separate watercirculating units having hollow end portions seated in said recesses andprovided with openings at their -rear sidesr corresponding in os1ti`onand number to the openings at the ase of each of said depressions,nipple projecting through a pair of said openings in each depression,re-enforcing tubes extending through said oiset Walls rearwardly of saiddepressions, elongated gaskets seated within said depressions, andclamping bolts extend-` y ing through said reenforcing tubes centrallybetween eachpair/of openings adapted to securey the units detachably inplace.

2. A radiator comprising an openfra'me havingI hollow water compartmentsat its top and bottom, thev walls thereof being made of sheet-metal andoffset 'angularly to provide transverse water passages and vertisaidbolt-openings sealed at their ends to the eoy interior of saidtransverse water passages yandgaskets seated within and confined attheir edges by the border walls of said depressions, in combination withvertical yvvater-circulziting and cooling units having hollow endcompartments and openings in therear walls thereof corresponding in poisition to said water-circulating and bolt openings in said seats, andclamping bolts for each unit extending through said bolt openings. y
